CHAIR.

Application filed May 25, 1914.-

To all whom it may concern Be it known that I, AUoUsT J. ALTHEIDE, acitizen of the United States, residing at Lewiston, in the county of NezPerce and State of Idaho, have invented certain new and usefulImprovements in Chairs; and I do declare the following to be a full,clear, and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in chairs and the primary objectof the same is to provide a chair of the'character described havingmeans for automatically forcing air against the body of a person sittingtherein as the chair is rocked.

A secondary object is to so locate the air discharge tubes as to renderthe air di cha-rged therefrom readily controllable by various movementsof the hands.

With the above objects in view, the invention resides in certain novelfeatures of construction and combination herein described and claimedand shown in the drawings wherein:

Figure 1 is a side view of my improved chair; Fig. 2 is a frontelevation thereof; Fig. 3 is a vertical longitudinal section on the line3-3 of Fig. 2; and Fig. 1 is a vertical cross section on the line 4-4lof Fig. 1.

In the embodiment illustrated, I have shown the base 1 of my improvedchair as comprising parallel side bars 2, said side bars being connectedby a plurality of transverse bars 3. Secured upon the cross bars 3 bymeans of L-shaped brackets 4, is a pair of base boards 5, whichconstitute the lower members of a pair of bellows 6, one of said bellowshaving its hinged end at the front of the chair, while the other bellowshas said end at the rear thereof. The upper movable members 7 of thebellows 6 are provided with funnel shaped valve casings 8 in which theusual outwardly opening valves 9 are disposed. Suitable inwardly openingvalves 10 are also employed in the base boards 5.

Mounted for oscillating movement upon the side bars 2 of the base 1 arethe rockers 11, which are curved upwardly at their front and rear endsand are secured in any suitable manner to side bars 12 which areconnected by front and rear cross bars 13 and let to constitute a framefor supporting.- the seat of the chair. Addi- Specification of LettersPatent.

Patented Feb. 23, 1915.

Serial No. 840,822.

tional cross bars 15 are also provided between said side bars 12 anddepending from said bars 15 are front and rear pivot studs 16 which arethreaded into the above mentioned bars and are pivotally connected bylinks 17 with similar pivot studs 18 on the movable members of thebellows 6.

A central cross bar 19 has its opposite ends secured to the side bars12, said bar being provided for supporting a four way coupling 20 whichcommunicates through flexible tubes 21 with each of the bellows 6, saidtubes being connected to the cone shaped valve casings 8. The coupling20 is also in communication with a pair of hollow arm supports 22 bymeans of flexible tubes 23.

As clearly shown in the drawings, a support 22 is arranged. on each sideof the chair and said supports extend through the arms 24: and havetheir bores turned slightly toward the rear as at 25 for the purpose ofdefleeting air in this direction.

I preferably pivotally connect the links 17 with the studs 16 and 18 bycotter pins 2 26 which are readily removable when it is desired to throweither one or both of the bellows out of operation. I may connect thefour-way coupling 20 in any desirable mannor to the cross bar 19, but Ipreferably employ a substantially U-shaped yoke 27 which is secured tosaid bar by screws 28.

In the operation of the device, aperson sits in the chair, and uponrocking back and forth, the bellows 6 will be alternately expanded andcontracted, thus forcing air through the tubes 21, into the coupling 20through the tubes 23 and into the bores of the arm supports 22, fromwhich it will be discharged through the rearwardly curved portions 25 ofsaid bores and will be forced against the body of the person sitting inthe chair. By manipulating his hands in the proper manner, the personsitting within the chair may direct the currents of air in any desireddirection and upon any part of the body. v

The chair may be rocked rearwardly, and if it is desired to retain it inthis position, one hand of the person reclining therein may be placedover the proper discharge opening 25 to prevent the escape of air. Thisoperation will, of course, prevent the expanded bellows fromcontracting, and therefore will prevent the chair from rocking forward.

I preferably construct my improved chair in the extremely popular typeknown as mission furniture, although it will be clear that the variousdetails of construction would operate to equal advantage were theyplaced on any other design of chair.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion, and minor details may beresorted to without departing from the spirit of the invention asclaimed.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent is: p

1. The combination with a base and a rocking chair resting thereon, saidchair comprising a'pair of rockers, a seat frame including a transversebar, a pair of arms spaced above the seat frame, and a pair of hollowarm supports rising from the side bars of the seat frame and being openat their upper and lower ends; of a coupling secured to said transversebar of the seat frame and having two outlets and two inlets openingsidewise, a pair of horizontal tubes leading from said outlets throughportions of the side bars of the seat frame and discharging into thehollow arm supports, a pair of bellows mounted on the base, connectionsbetween said bellows and the chair to actuate the former as the latteris rocked,

depending feet at their opposite ends, and

a plurality of transverse strips extending fromone side bar to theother, and a rocking chair whose rockers rest upon said side bars, saidchair including a seat frame having a pair of transverse bars locatednear its front and rear sides, and a third transverse bar located nearits center; of a pair of oppositely facing bellows having rigid basesresting upon and secured to the transverse strips of the base, linksrising from the free ends of the two bellows and pivoted respectively tothe front and rear transverse bars of the seat frame, a four-waycoupling'secured to the central transverse bar of said seat frame, apair of tubes leading from the two bellows to said coupling, and asecond pair of such tubes leading outwardly from said coupling and thenupwardly to points 7 above said seat frame.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
